He Made Me Cum Weirdly

One of the many things about my husband that I really admire is his inventiveness. Like, the other day, we were in bed, and started to get in the mood, if you know what I mean. He instructed me to lay on my tummy with my legs spread apart. I was expecting butt fucking or something. Instead, he just lightly touched the area around my anus, about an inch away. He stroked that whole area without ever touching the middle. And he kept doing it. Lo and behold, after three or four minutes of that, I felt that feeling that you ladies will know so well. The pit of the stomach, the chills, the tightening of the vagina, and then it happened, I had an amazing orgasm without ever having been penetrated, licked, or anything at all. Just the very light massaging of the area around my asshole. And, he didn't stop. He just kept right on going past all my squirming and yelling, and after a minute I had another orgasm just as strong as the first. And, I don't know about you ladies, because I know some women are multi-orgasmic, but that's the first time in my life I had two complete O's in a row.  The only problem is, now I have to come up with something inventive for him. Some new kind of handjob or something. Any ideas?
